WAGON-STARTER.

SPECIFICATION forming part of Letters Patent No. 469,758, dated March 1,1892- Applioation filed February 24, 1891. Serial No. 382,639. (Nomodel.)

provide a simple and effective mechanism for attachment to a wagon, soas to afford an ef-:

fective and powerful means for starting the same when from any cause thesame has become stalled, the draft of the horses being.

employed to operate the attachment, as will hereinafter more fullyappear.

In the accompanying'drawin gs, illustrating mypresent improvements,Figure 1 is a plan View of the front'portion of the running-gear of awagon to which my present improvement is applied; Fig. 2, a detailsectional elevation on line 0c 00, and Fig. 3 a detail sectional planview'of the clutch that engages the rim of the Wagon-wheel.

Similar numerals of reference indicate like parts in the differentviews.

Referring to the drawings, 1 represents the front wheels; 2, the axle;3, the bolster or lower member of the fifth-wheel, and lt-the hounds, ofthe usual form and construction.

In the present invention the tongue 5 is capable of alimitedlongitudinal movement between the bounds 4:, and such longitudinalmovement may be circumscribed by an elongated slot 6, formed in its rearportion and made to engage around the ordinary king- 'bolt 7, asillustrated in Fig. 1. Dependence,

however, is placed more upon the cross-piece or bar 8, arranged on topof the tongue and secured thereto by bolt 9 and yoke-brace 10, such baror piece 8 sliding along the tops of hounds 4 and in its forwardmovement coming to a stop against the fixed cross-piece 11 of saidhounds.

12 is an orifice down through the cross-piece 11 and the tongue 5 forthe passage of a bolt or pin to lock the tongue in its rearward positionfor the purpose hereinafter stated.

The mechanism forimparting motion to the wheels of the wagon is of adual arrangement, one for each wheel, and each consisting of a radialbar or arm 13, journaled to the axle by the pivot-bracket 14, andcarrying at its outer end the grip-lever 15. This grip-lever 1s pivotedat its middle on the radial arm 13, its

outer rim and sides of the wheel, as shown, while its inner end isconnected by a link or rod 16 to the respective end of the cross-bar 8of the tongue, the construction being such that an initial longitudinalmovement of the tongue in its hounds will first draw the griplevers intooblique positions, so as to clamp o r grip the wheel-rims, and withfurther longitudinal movement of the tongue will impart motion to thewheels to start the wagon.

17 is a stop or lug on the side of each draw link or rod 16, againstwhich the side of the grip-lever abuts to be held in parallel andnon-engaging position when the starter is in its retracted position, asindicated in Fig. 1.

With the construction shown when the tongue in its forward movementcomes to a a parallel or non-engaging position, so as not to interferewith the further movement or rotation of the wheel.

18 is a back-stop on the axle to limit the rearward movement of theradial arm 13 and hold the parts in operative position.

In the construction shown, owing to the differences in the pivotal axisof the wheel and the radial arms of the grip mechanism, means arerequired to allow for an expansion and contraction of the radial arms,so that the same radial distance of the grip-lever from the axis of thewheel will at all times be preserved. I accomplish this in a veryeffective manner by a sleeve connection 19, that forms both the pivotalconnection for the grip-lever, as well as an expansion-joint, for thepurpose above stated..

V In my present improvement the distinguishment of theconcentrically-acting grip mechanism for imparting a simultaneousstarting movement to the wheels of the wagon, and in the practicalcarrying out of my invention modifications may be made in the structureand mechanical arrangement of the parts outer end being bent so as tostraddle the ing feature is the independent dual arrange stop thegrip-lever will automatically assume without departing from the spiritof this part of my'invention. Among such may bementioned the applicationof the starting mechanism to the hind wheels of the wagon instead of tothe front wheels, as shown, the substitution of a yoke connectionsurrounding the axle to form a pivotal connection for .the 'radial arm13 instead of the pivot-bracket 14, as well as the use of any otherusual and Suitable gripping device for the special form of grip-lever 15illustrated in the drawings.

Having thus fully described my said in vention, What'I claim as new, anddesire to secure by Letters Patent, isr 1. The combination, with awagon-tongue adapted to have limited longitudinal movement and carryingacross-bar, of .the dualarrangementref radial arms pivoted totheaxleandcarrying at their outerendsa; grip mech anism adapted to.engagethewheels, substan-; tially asset forth. ;2. Thecombination withawagon-tongue adapted to. have limited longitudinal movement andcarrying a cross-bar. fixedlybracedl thereto, of the duaLa-rrangement ofradial arms pivoted to the axle and carrying at their outer ends apivoted grip-lever,- one end of] which is bent or channeled to engagevthe? wheel-rim and the other end. formed ithanj eye for the attachmentof theconnectin rrods betweensaid grip-levers and .the endsofgtheicross-bar on the tongue, substantially. as set;

3. The combination, with a wagon tonguef adapted to have limitedlongitudinal move-: ment .and carrying a cross-bar fixedlybracedthereto, of the dual arrangementof radial arms pivoted to the axle andcarryingat their outer ends a pivoted grip-lever, one.endof which isbent or channeled to engagethe wheelerimand the other. end formedwithaneye for the attachmentof the connecting-rods betweenfisaid grip-leversand theends of the cross-bars on the tongue, and a back-stop 18 on theaxle to limit the rearward movement of the radial arms of the gripmechanism, substantially as set forth.
